SPECIFICATION forming part of Letters Patent N0. 526,724, dated October 2, 1894.

Application filed July 10, 1894. Serial No. 517,051. (No model.)

To all whom it may concern.-

Be it known that I, CARL J. MAYER, a subject of the Emperor of Germany, and a resident of Lynn, in the county of Essex and State of Massachusetts, haveinvented new and'useful improvements in Fleshing-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in fieshing machines for the purpose of removing fat, flesh and loose membrane from the flesh side of skins and hides and it consists in means for automatically holding the skin supporting roller and the skin held thereon with a proper pressure against the rotary fleshing knife roller as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein Figure 1, represents a top plan view of the Fig. 2, represents alongitudinal 3, represents a side elevation seen from X in Fig. 1. Fig. 4:, represents a detail section on the line 4-4 shown in Fig. 1. Fig. 5, represents a detail top plan view of the releasing lever shown in Fig. 4. Figs. 6 and 7 represent in side elevation and top plan the cam for actuating said releasing lever. Fig. 8, represents in top plan and side view the bearings for the skin supporting roller. Fig. 9, represents a detail front elevation of one of the bearings for said skin supporting roller; and Fig. 10, represents a detail top plan of the yoke for said roller bearing.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings A represents the frame or standard of a fleshing machine as usual in bearings in which is journaled the driving shaft 5, to which the rotary knife roller B is secured as usual.

B and B" are the respective loose and fast pulleys on the shaft 17 as usual.

To the frame A are secured the usual horizontal guide rods 0, C, on which the clamp bars D, D are guided. Said clamp bars are adapted to clamp one end of the skin between them by means of any well known clamping or locking device (1, d, shown in Fig. 1, as is common in machines of this kind.

the teeth of an intermediate gear G loosely journaled on a stud g and meshing in a pinion l-I secured to a pulley h journaled on a stud or shaft H as shown in- Fig. 3.

From the pulley It leads a slack belt I to a pulley K secured to the shaft is which is journaled in bearings in the frame A as shown in Figs. 1, 2 and 3.

At Z is pivoted the belt tightener lever L provided with a pulley L which is adapted to be brought against the slack belt I when the leverL is swung upward and for this purpose I prefer to attach to said lever L a cord or strap l which is guided over a pulley or roller Z" journaled in a bearing secured to any stationary object over head as shown in i Fig. 3 and preferably provided with a suitable handle Z as shown in said Fig. 3 for the operator to take hold of whenever it is desired to set the pulley K and its shaft 7c in rotation.

D are standards secured to the forward ends of the horizontal guide rods 0, C, as shown in Fig. 2.

To the shaft is secured a pair of chain pulleys K K to which are attached one end of the respective chains M, M, which are guided in stationary posts N, N, and carried over pulleys d d journaled on pins at the forward ends of the guide rods 0, O, as shown in Figs. 1 and 2 and secured to the clamping bar D as shown. On the shaft 7.: is secured a pair of cam disks k is each such cam disk having a peripheral notch or recess 70 adapted to receive a pin or pin and roll 0 on the levers O 0' which are pivoted at O 0" and provided in their forward ends with adjustable bearings 19,19, in which the shaft 19 of the pressure roller P is journaled. The pressure roller]? is set in a rotary motion in direction of arrow shown in Fig. 3 when the skin is introduced between it and the knife roller B by the following mechanism.

On the shaft Z2 is secured a friction pulley 1) adapted to bear against a friction pulley Q secured to a pin or shaft q journaled in a bearing attached to or forming part of the frame A. On said shaft (1 is secured a chain 7 i an N A- the chain q is kept taut so as to causethe roller P to rotate inkthe direct-ion shown by arrow thereon in Fig. 3 and thus cause the skin to be fed between the said roller P and knife roller B during the forward motion of I the clamping bars D D. After the said p ng" bars D D have been moved with; the skin held between them to the limit of; their stroke relative to the supporting roller i P the operatorpulls down on the handle Z bywhich the lever L is rocked sufficiently to bring the belt tightener L against the belt I bywhich the latter is tightened sufliciently to impart motion to the shaft is, its pulley K, chain pulleys K K and earns is causing the pin and rolls 0 on the levers O to :move

out of the cam recesses k" by which the levers O arerocked and their forward ends automatically raisedsufficiently to bring the roller P and the skin carried thereon in yielding contact with the rotary fieshing roller B at the same time as the clamping bars D D and the skinclamped betweenthem are drawn toward the operator by the :infi-uence of the chains M M-andthe chain wheels K K thus causing the knives on the fles'hing roller B to remove the. flesh and fatty sub stances from the skin; andwhenithe roller P is thus held raised its chain q is slackened allowrngit to rotate freely in an opposite direction to that shown by arrow in Fig. 3 thus enabling the skin to be drawn freely toward the operator during the fleshing operation.

clamps D D and reverses its position and clamps the opposite end thereof between the clamps D D and proceeds with such other end of the skin in a similar manner.

For the purpose of aiding in returning the pulley K to its original position shown in Figs. 3 and 4 I provide it with an adjustable counter weight K shown in Figs. 2 :and 4 whlch in connection with the chains M M as the clamps D D are pushed toward the roll P causes the shaft in and its connections to be automatically returned to the locking position shown in Figs. 2, 3 .and 4.

For the purpose of adjusting the roller P to and from the knife roller B I employ a pair of handles R R attached to screws 4 r journaled in bearings o 0 in the front end of the levers O 'O and screwed through the'bearings p 10 as shown in Fig; 4; and for the purpose of causing the said roller P to yield to and from the knife roller B to compensate for inequalities in the thickness of the skin or hide that is being fleshed I secure to each of said levers O a yoke S between which and the,

under side of each of said bearings 19 is located a spring S on a spindle S as shown in Fig. 4. To compensate for such yielding of the roller P I make the front bearings o of the spindlesRR slotted as shown in Fig. 4. By turning the handle R and its screw spindle 'r, the bearings p, p for the shaft of the roller P may be adjusted to and from the rotary knife roller B according to the thicknessofth-e hide that is being fleshed. The spring S interposed between the under side of each bearing p and the yoke S normally holds said bearings with a yielding pressure in their highest position and allows said bearings and the roll P journaled therein to yield automatically relative to inequalities in the thickness of the hide that is being fleshed.

The operation of this my improved fleshing machine is as follows: The knife roller B is continuously rotated in the direction shown by arrow in Fig. 2, as-are likewise the pulleys B and F, intermediate gear G and pulley h in direction of arrows shown in Fig. 3. The operator then takes :a skin and clamps \one end thereof between the clamping bars D D and places the opposite end between the rotary feed roller P and knife roller B and pushesthe said clamping bars toward the feed roller P which by its rotation causes the skin wit-h the flesh side uppermost to be fed freely between said rollers P and 13 without being acted upon by the latter during such feed of the skin. Theope-rator then pulls downward on the handle Z by which the belt tightener L is brought against the slack belt I causing the shaft Fla with its pulley K, cams 10 7t and chain pulleys K K to be rotated apart of a revolution in the direction of arrow shown in Figsr2and 3and in so doing the pin and rolls 0 atxthe rear ends of the levers O are depressed by the camsk is causing the roll P to be raised After one end of the skin has been fleshed, 1 the operator removes it from between the sufficiently to bring the flesh'side ofathe skin in proper contact with the rotary fies-hing knife 3 andwca'usi'ng the roller P to be disengaged from the chain pulley q and while the skin is thus being acted on by the fleshing roller B it is automaticallydrawn toward the operator by thechainwheels K K and the chains M M connected to the clamping bars D D until the skin is entirely drawn free from the fleshing roller. The operator then detaches the skinfrom between the clamping-bars and reverses its position therein by securing the now flesh-ed end between the clamping bars and as the latterare pushed toward the feed roller P the chains M M are tightened caus ing the chain wheels K K and earns k k to be reversed and returned to their normal positions shown in Figs.- 2 and 3 aided by the counterweight K after which. the operator proceeds as before stated to flesh the remaining portion of the skin by pulling down the handle Z and thereby causing the roller P to hold the flesh side of the skin in contact with the rotary fleshing roller B and causing it to be drawn from between the latter and the feed roller P and so on during the operation of the machine.

What I wish to secure by Letters Patent and claim is- 1. In a fleshing machine a rotary knife roller and longitudinally movable clamps adapted to slide to and from the knife roller in combination with a feed roller journaled on pivoted levers and cams 7c is for automatically actuating said levers to hold the skin against the knife roller during the fieshing operation substantially as and for the puroperating said cams and causing the feed roller to automatically hold the skin in contact with the rotary knife roller during the fleshing operation substantially as and for the purpose set forth.

3. In a fieshing machine a rotary knife roller and longitudinally movable clamps combined by a cam shaftk having camsk' k pivoted levers O O actuated by said cams a starting device for operating said cams and a feed roller journaled in longitudinally adj ustable and vertically yielding bearings at the forward ends of said pivoted levers substantially as and for the purpose set forth.

4. In I a fieshing machine a rotary knife roller and longitudinally movable clamps and connecting chains from the latter to chain wheels K K on a cam shaft is having cams k 70" and balance weight K" combined with pivoted levers O O a feed rollerP journaled at their forward ends and means for actuating said cam shaft substantially as and for the purpose set forth 7 r i In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 2d day of July, A. D. 1894.
